Upon rotation out of laredo; we felt a slight bump or thud as the aircraft left the ground. The crew agreed that it was most likely a gust of wind; not strong or loud enough to be alarming; just noticeable. We landed at destination with no problem; the aircraft touched down; stopped and taxied normally. During postflt the inboard tire on the #1 side of aircraft looked like the entire tread had been peeled off the aircraft. The tread had wrapped itself around the wheel between the strut and the remaining tire; and around some of the braking mechanisms; stretching part of the tire over the brake line and evidently breaking the line causing a steady flow brake hydraulic fluid leak. Maintenance and a hazmat team were called to clean up the spill and fix the tire.
